First, and foremost, kudos and infinite thanks to knaerzche for this libreelec. I bought a Mitzu (that's the outside brand) years ago, and it was a piece of crap. Unusable.
But with this img I was able to revive it. I installed Jellyfin and I can see my movie collection in a big screen. Just priceless.
The thing is that i cannot install any other add-on, not netflix, not aptoide ---I want it just for Stremio---, not ares wizard, not hbo (those are the most important add-ons from me right now).
My board is a R329Q v 3.1, with rk3229.
The img I used was LibreELEC-RK322x.arm-9.80-devel-20200228171244-cd590c7-rk3229-box.img.gz (no other booted, not even one from the legacy 9.2).
Here are the logs
And finally, I'm not a technology wise user. Just to boot, the libreelec img was a though one for me. But I'm willing to learn if someone is willing to give a hint.
Thanks to you all!
